ragged on both sides : but from what remains of the anal patch, it appears to be of the same 
character as that of T. amta). Body white, the venter creamy, the tarsi aunulated with 
black. Expanse of wings 1 inch 3 lines.

Fryer's figure of Z. (T.) signata is a very indifferent one and barely recog- 
nizable ; he states that the species is not uncommon in Yesso. I have three 
specimens from that island, which differ hiter se and from the type, figured in 
' Aid,' in the character of the white basal marks on the under surface.

" I received three bred specimens of this very interesting new species from Dorries, all of which 
appeared to be females, and closely resembled the same sex of T. quercus on the upper 
surface, but the pale blue ol discoidal cell is continued beyond in the form of a streak in each 
median interspace. The basal portion of the secondaries, especially the cell, is suffused with 
blue, and the white-tipped black tail is distinctly longer than in T. quercus. The fringes are 
dark, hut in one specimen chequered, especially on the secondaries, with white. Under 
surface ochreous slightly tinted with grey, differs from aU other species of Thecla (from the 
Paloearctic or Indian Fauna) in having white markings at the base of the secondaries. The 
large orange anal spot wcU defined. Antennoe black, ringed with white, with less brown at 
the tip than in quercus; the pectus is clothed with bluish-white hair; the white fiet are out- 
wardly marked with black ; the tarsi are white, ringed with black, and the abdomen is dark 
above and yellowish white beneath. 
" The larva lives on oak, and is green with brown spots along the back and sides. The first three 
segments have some darker (blackish) spots, and are clothed with longer and thicker hair 
than the others ; the eleventh segment has a somewhat remarkahle conical process, which is 
not familiar to me in the case of any other Lycaenid larva." (StaudiM/er, I. c.) 
Staudinger states that his description of quercivora is taken fi-om three bred 
examples of the female fi'om Amurland, but his figure is said to represent 
a male. 
Two female specimens, kindly lent to me bv Mr. Grose Smith, one fi-om 
Ichang, Central China, and the other fi-om Western China, probably Omei- 
shan, agree with quercivora, except that the secondaries have more blue on 
the upper surface. The figure of Z. quercivora agrees vdth the figm-e of 
Z. signata in every particular but the character of basal marks on under 
surface ; and as I find that these marks are inconstant in Z. signata, 1 am 
disposed to think that when more material is available it A^ill be found that 
quercivora is only a form of Z. signata. If Dr. Staudinger had been acquainted 
■mtli the latter species, he certainly would have compared his quercivora with 
it rather than with quercus.
